JAR-CLOSURE.

Specification of Letters Patent.

Patented April 14, 1908.

Application led November 1, 1906, Serial No. 341,597. Renewed October30, 1907. Serial No. 399,787.

To all whom it may concern:

Be it known that I, PETER J. LAYMAN, a citizen of the United States ofAmerica, residing at Akron, in the county of Summit and State oi Ohio,have invented certain new and useful Improvements in Jar-(losures, oiwhich the following is a specification, reference being had therein tothe accompanying drawing.

rlhis invention relates to receptacle closures, and the inventionrelates more particularly to a closure designed for jars, as fruit andmilk jars.

The invention has lor its primary object to provide a simple andinexpensive closure, wherein positive and reliable means are employedfor locking a cap or similar closure in engagement with a jar.

.Another object of this invention is to dispense with the use of corksand stopper clasps heretofore used for closing small receptacles.

To this end, I construct aar or similar receptacle with an annularliange adapted to support a cap and with inwardly projecting lugs adated to lock a washer upon said cap, said waslier being constructedwhereby when it is placed in engagement with a jar or similarreceptacle, the cap will b e firmly held upon the annular llange of saidreceptacle, thus insuring a positive closure of said receptacle.

The detail construction of my improved closure will be presentlydescribed and then specifically pointed out in the claims, and referringto the drawing forming part of this specification, like numerals ofreference designate corresponding parts throughout the several views, inwhich Figure 1 is a vertical sectional view of a jar equipped with myimproved closure,v

Fig. 2 is a front elevation of a Wrench employed for opening the jar,Fig. 3 is a side elevation of the same, Fig. 4 is a plan of aclosure-disk constituting one of the elements of the closure, Fig. 5 isa plan of my improved closure, as applied to a jar, Fig. 6 is a sideelevation of the closure-disk, Fig. 7 is a similar view of a modiiiedform of closure-disk, Fig. 8 is a perspective view of the securingwasher which locks the closure disk in position in the holder orreceptacle. Fig. 9 is a plan view of a modified construction in whichthe closure-disk and washer are integral.

To put my invention into practice, I construct the opening or neck end 1ol' a jar or similar receptacle with an interior annular shoulder orl'lange 2, located a slight distance below the upper end of thereceptacle, and at the upper end with inwardly extending equally spacedlugs 3, said lugs being segmentshaped and occupying approximatelyonehal'i the circumference of the'jar or receptacle.

Upon the annular shoulder 2 is adapted to rest a closure-disk 4 having adepending portion 5 'fitting snugly within the inner wall of the flange2 and an upwardly extending circular portion 6. The closure disk may, ifdesired, have a washer or gasket 5 surrounding the depending portion 5as shown in Fig. l, to effect a close union with the flange 2. After theclosure-disk is placed upon the shoulder 2 of the jar or receptacle, awasher 7 is placed over the portion 6 of the closuredisk, said washerhaving radially disposed lugs 8 corresponding to the spaces 9 formedbetween the lugs 3 of the jar or receptacle. The lugs 8 are formed withbeveled ends 10, and said washer is provided with diametrically opposedopenings 11, whereby a wrench 12 can be placed in the openings 11 torotate said washer and cause the lugs 8 to ride along under the lugs 3of the jar or receptacle. The beveled ends 10 of the lugs when beingforced under the lugs 3 cause the washer 7 to seat rmly upon theclosure-disk 4, and thereby force said closure-disk downwardly upon theshoulder 2 insuring a non-leakable closure for the jar or receptacle.

The wrench 12 which I use in connection with the washer 7 is preferablyconstructed of a piece of wire, bent to provide depending ends 14adapted to fit within the openings 11 of the washer 7, and twisted toform a handle 15, whereby the wrench can be easily and quicklymanipulated to remove the Washer from the jar or receptacle.

In Fig. 7 of the drawings, Ihave illustrated a modified form ofclosure-disk 4a wherein the edges of the disk are beveled as at 4b toinsure a more positive closure of thej ar or receptacle,

while inFig. 8 of the drawings, I have illustrated afurther modificationof the invention,

in which the closure-disk 7 a and washer 7l" are made integral, thisconstruction being particularly adapted for bottles and similar smallreceptacles. To insure a positive connection between a jar and thedevice illustrated in Fig. 8, a gasket of rubber or cork (not shown) canbe readily used.

I do not care to confine myselil to the type CIK of jar or receptacle inconnection With which my improved closure is used, or to the size,proportion or minor details of the same.

What I claim and desire to secure by Ile-tters Patent, is

1. In combination with a jar' having an interior annular shoulder, andinwardly-projecting lugs carried by said jar above said shoulder, aclosure-disk adapted to rest on the shoulder and having a circulardepending portion fitting with the circular inner Wall of said shoulder,and. a Washer engaging the Closure-disk having a plurality ofradially-disposed periplieral-lugs adapted to take under and engage withthe lugs of the 2. In combination with a jar li aving an interiorannular shoulder, and inwardly-projeoting lugs on the inner face of thear above said shoulder, a closure-disk resting on the said shoulder andhaving a depending circular portion iitting With the inner Wall of theshoulder, a Washer engaging the closure-disk and havingdiametrica-lly-opposed Wrenchreceiving openings, and peripheral-lugsoarried by said Washer to take under and engage with the lugs in thejar, each lug on the washer having a beveled end., as and for thepurpose described.

In testimony whereof I aHiX my signature in the presence of twoWitnesses.

PETER J LAYMAN.
